Description
Technical Field
The invention relates to the field of battery thermal management, in particular to a wireless charging-heating integrated system for a battery, a control method and a battery system.
Background
The charging and discharging performance of the lithium ion power battery is rapidly deteriorated under the influence of low-temperature environment, the winter driving range of the electric automobile is seriously influenced, and the service life of the battery is permanently damaged. Therefore, in a low-temperature working environment, the power battery is preheated before the electric automobile normally runs, so that the battery cell reaches a normal working temperature range, and the working performance of the battery cell is improved.
The low-temperature heating of the battery is a powerful means for ensuring the efficient, lasting and safe operation of the power battery in a low-temperature environment. The common modes of low-temperature heating of the battery can be divided into two modes, namely external heating and internal heating, according to the position of a heat source.
The external heating method generally transfers heat from outside to inside to the power battery by heating air, coolant, and heat transfer media such as heating wires, and by means of thermal convection or thermal conduction. Such as the battery heating system disclosed in patent document CN 105633506B. Due to the long heat transfer path, the heating rate of the external heating method is slow, and the temperature distribution of the power battery is extremely uneven. Meanwhile, in the heating process, more heat exchange exists between the external heat transfer medium and the cold environment, the heat loss is large, and the heating efficiency is low. Therefore, the external heating method is difficult to continuously and effectively meet the optimal working temperature of the power battery in a low-temperature environment.
The internal heating method is that the power battery generates current through charging and discharging, the current generates ohmic heat by using the internal resistance of the battery, and the power battery is directly heated from the inside of the battery core. Through setting up the heat source inside electric core, can reduce the route of heat transfer, avoided the direct thermal coupling of heat source and external environment simultaneously, heat loses very little. Therefore, the internal heating method is fast in heating speed and high in efficiency. In addition, the heating heat source is uniformly distributed in each battery cell, so that the uniformity of the temperature field distribution is obviously improved compared with that of external heating. Therefore, internal heating of power cells has significant advantages and potential for development over external heating methods.
The existing internal heating method generally adopts alternating current for heating, and can be divided into two different modes of external equipment power supply and power battery self-power supply according to different power supply sources. In consideration of flexibility of application scenarios, a power battery is becoming a mainstream heating method in a self-powered manner. In order to generate sinusoidal alternating current heating current, the structure of heating equipment in the power battery is complex, the volume and the weight are both large, and sufficient installation space needs to be reserved on the electric automobile. Meanwhile, hardware of the battery heating equipment is expensive, and extra cost of the electric automobile is increased. Therefore, the volume and cost become the technical bottleneck of the internal heating system of the power battery, and the application possibility of the internal heating method is greatly limited. Meanwhile, the power switch of the existing battery internal heating system generally works in a hard switch state, and the efficiency and the reliability are not ideal.

Detailed Description
The present invention will be described in detail with reference to specific examples. The following examples will assist those skilled in the art in further understanding the invention, but are not intended to limit the invention in any way. It should be noted that it would be obvious to those skilled in the art that various changes and modifications can be made without departing from the spirit of the invention. All falling within the scope of the present invention.
The invention provides a wireless charging-heating integrated system for a battery, which comprises: two bridge arms;
each of the bridge arms includes: the power tubes are sequentially connected in series from head to tail;
a receiving coil: connecting the middle point of each bridge arm through a compensation circuit;
a battery: the positive pole is connected with the positive pole of the direct current bus of the bridge arm, and the negative pole is connected with the negative pole of the direct current bus of the bridge arm.
In the embodiment provided by the invention, the power battery (battery pack) of the electric vehicle is taken as an example, but those skilled in the art know that the application of the invention is not limited to the electric vehicle.
As shown in figure 1, the main power circuit of the wireless charging vehicle-mounted receiving end is composed of 4 MOSFET power tubes S1-S4And (4) forming. The power battery is connected with the bus of the main power circuit at the receiving side in parallel, VbRepresenting the open circuit voltage, R, of the power battery packbAnd the equivalent ohmic internal resistance of the power battery pack is shown. L is2For wireless charging vehicle-mounted receiving coil, the compensating circuit is connected in parallel with the receiving coil. The receiving side compensation circuit network has various topologies, such as capacitance series compensation, parallel compensation, LCC type compensation and the like. The wireless charging-low temperature heating integrated system for the power battery of the electric automobile can be compatible with various compensation network topologies, and can realize sine wave alternating current heating of the battery. During operation of the heater, to prevent energy from being transferred to the wireless charging transmitting terminal, the transmitting terminal coil switch may be turned off, so that the transmitting terminal portion of the wireless charging system is omitted from the drawing because it does not participate in the operation of the heater.
When the wireless charging-low-temperature heating integrated system for the power battery of the electric automobile heats the battery, the power tube S of the main circuit power converter1-S4Driven by two complementary PWM high-frequency signals, where S1And S3Are simultaneously switched on and off, and S2And S4And simultaneously, the switch is switched on and off, and the duty ratio of each switch is 50%. Taking the most common receive side series compensation for wireless charging of an electric vehicle as an example, the operation mode and principle of the internal heater of the battery can be described as follows in conjunction with fig. 2:
(1) driven by PWM signal, when power switch S1And S3When on, the equivalent circuit of the heating system is as shown in FIG. 2aAs shown. Power battery VbThe energy is exchanged with a wireless charging vehicle-mounted receiving side resonant circuit, and the resonant frequency is
At this time, the circuit equation can be expressed as:
Vbdischarging the resonant branch circuit, and storing energy into a resonant loop; when the resonant tank voltage stores energy to a certain extent, its voltage will be higher than the power battery voltage, at this moment, the energy will be fed back to the power battery. Through the energy exchange process, the power battery is charged and discharged at high frequency during the process, and heating current approximate to sine wave is formed.
(2) Driven by PWM signal, when power switch S2And S4When on, the heating system equivalent circuit is shown in fig. 2 b. Compared with the previous state, the power battery VbThe connection polarity of the wireless charging vehicle-mounted receiving side resonant circuit is opposite to that of the wireless charging vehicle-mounted receiving side resonant circuit, but energy can be exchanged similarly, and the resonant frequency is also equal to
At this time, the circuit equation can be expressed as:
Vbsimilarly, the resonance branch is firstly discharged, and energy is stored in the resonance loop, but the current direction of the resonance loop is opposite to that of the previous state; when the resonant tank voltage stores energy to a certain extent, its voltage will also be higher than the power battery voltage, feeding energy back to the power battery. Through the energy exchange process, the power battery is charged and discharged at high frequency during the process, and heating current approximate to sine wave is formed.
Since the working frequency of the wireless charging vehicle-mounted receiving end equipment is generally about 85kHz, the wireless charging vehicle-mounted receiving end equipment resonates backThe resonant frequency of the circuit is also relatively high. The wireless charging-low temperature heating integrated system utilizes the receiving side resonant circuit to store energy, so that the working frequency is higher, and the loss of the power switch tube is larger. To improve the efficiency of the heater system while enhancing the safety and reliability of its operation, the power switching tube must be operated in a soft switching state. For the MOSFET switching tube, Zero Voltage Switching (ZVS) is an ideal working state, and can avoid efficiency reduction caused by switching loss. Therefore, the wireless charging-low-temperature heating integrated system for the power battery can adjust the switching frequency fsAnd the MOSFET tube is enabled to work in a ZVS state. The specific implementation mechanism can be illustrated with reference to fig. 3: at the moment, the switching frequency f of the wireless charging-low-temperature heating integrated system of the power battery issCan be set to less than 0.5 times the resonant frequency, i.e., fs<fr/2. With S1For example, before the turn-on pulse signal of the MOSFET comes, the anti-parallel diode starts to conduct and freewheel, so that the voltage drop V is reduced when the MOSFET is turned ons1Basically 0, no turn-on loss, and greatly reduced switching loss.
According to parameters of corresponding elements of a power battery and a wireless charging vehicle-mounted receiving end resonant circuit, a heating current time domain expression of the power battery wireless charging-low temperature heating integrated system is as follows:
Ib＝C2e-αt[(-αλ1+βλ2)cosβt-(αλ2+βλ1)sinβt]
wherein the content of the first and second substances,
(L has been changed to L2Inductance of the receiving coil for wireless charging, e is the natural logarithm base, generally without additional explanation, Ts＝1/fsThe formula is modified correspondingly
It can be seen that the effective value of the heating current of the low-temperature alternating-current heating system of the invention follows the switching frequency fsAnd characteristic impedance of resonance element
And (4) changing. After the result is normalized, the multiplying power of the effective value of the alternating-current heating current is as shown in fig. 4, the corresponding switching frequency of the heater can be determined by adopting a table look-up method according to the maximum allowable charging and discharging current of the power battery to be heated at the corresponding temperature and the parameters of the resonant element of the heater, the low-temperature heating alternating current is adjusted, the effective value of the alternating-current heating alternating current is lower than the maximum allowable charging and discharging current of the power battery at the current temperature, and the safety and the reliability of the low-temperature heating are ensured.
On the basis of the wireless battery charging-heating integrated system, the invention also provides a control method of the wireless battery charging-heating integrated system, and the wireless battery charging-heating integrated system adopts the two-way power supply resonant alternating current heating system to execute the following operations:
